The city is characterized by a Mediterranean climate, with long, hot summers, with extreme temperature changes during the day, and mild winters, although due to its proximity to the Daunian mountains the temperature can drop to values below 0 °C (32 °F). The winds are quite frequent and, although sometimes quite strong, are usually moderate.

The average annual temperature is around 15 °C (59 °F), and rainfall amounts to an average value of 497 millimetres (19.6 in). Snowfalls are rare.

Lucera is located in the territory of the Dauni ancient tribe. Archeological excavations show the presence of a bronze age village inside the city boundaries. Lucera was probably named after either Lucius, a mythical Dauno king, or a temple dedicated to the goddess Lux Cereris. A third possibility is that the city was founded and named by the Etruscans, in which case the name probably means Holy Wood (luc = "wood", eri = "holy").

In 321 BC, the Roman army was deceived into thinking Lucera was under siege by the Samnites. Hurrying to relieve their allies the army walked into an ambush and were defeated at the famous Battle of the Caudine Forks. The Samnites occupied Lucera but were thrown out after a revolt. The city sought Roman protection and in 320 BC was granted the status of Colonia Togata, which meant it was ruled by the Roman Senate. In order to strengthen the ties between the two cities, 2,500 Romans moved to Lucera. From then on, Lucera was known as a steadfast supporter of Rome.

During the civil wars of the late Republic, Pompey set up his headquarters in Lucera, but abandoned the city when Julius Caesar approached. Lucera quickly switched its allegiance and Caesar's clemency spared it from harm. In the next civil war between Octavian and Mark Anthony the city did not escape as lightly. After the war, Octavian settled many veteran soldiers on the lands of the ruined city. This helped Lucera recover quickly and marked an era of renewed prosperity. Many of the surviving Roman landmarks hail from this Augustan period, among them the Luceran amphitheatre.

With the fall of the Western Roman Empire the city of Lucera entered into a state of decline. In 663 AD, it was captured from the Lombards and destroyed by the Eastern Roman Emperor Constans II.

In 1224, Holy Roman EmperorFrederick II, responding to religious uprisings in Sicily, expelled all Muslims from the island, transferring many to Lucera (Lugêrah, as it was known in Arabic) over the next two decades. In this controlled environment, they could not challenge royal authority and they benefited the crown in taxes and military service. Their numbers eventually reached between 15,000 and 20,000, leading Lucera to be called Lucaera Saracenorum because it represented the last stronghold of Islamic presence in Italy. During peacetime, Muslims in Lucera were predominately farmers. They grew durum wheat, barley, legumes, grapes and other fruits. Muslims also kept bees for honey.[2]

The colony thrived for 75 years until it was sacked in 1300 by Christian forces under the command of Charles II of Naples. The city's Muslim inhabitants were exiled or sold into slavery,[3] with many finding asylum in Albania across the Adriatic Sea.[4] Their abandoned mosques were demolished, and churches were usually built in their place, including the cathedral of S. Maria della Vittoria.[5]

After the Muslims were removed from Lucera, Charles tried to settle Christians in the city. Those Muslims that converted to Christianity got part of their property back, but none was restored his former position of political or economic influence. As time progressed, grain production fell in the city, and in 1339 the city was hit by a famine. Christians were allowed to farm as the Muslims.[6]

the Roman Amphitheater, dating to Augustus' times and one of the largest in southern Italy. It was discovered in 1932: during the excavations, a statue of Augustus was found in the site. It measures c. 131 by 99 metres (430 by 325 ft), of elliptical plan, and could host from 16,000 to 18,000 spectators. The area measures 75.2 x 43.2 m.[clarification needed] The amphitheater could be accessed from two large portals, one towards Lucera and one towards Foggia; the two side accesses, as well as the external walls, are no more visible. It was perhaps destroyed in the capture of the city by the Eastern Roman Emperor Constans II in 663.
